'of New Yicrk, have invented new and useful Improvements in Gart0n-Fillers, =of which I the following is a specification.

My invention relates to machines for an.-

tomatica'lly measuring the contents and dilling cartons.

The object 10f any invention \is to produce a machine for filling cartons with a predetermined quantity of zgranular or flalay' substances from a. reservoir er bin containing same.

Alfunther object thereof is to produce a plurality of measuring buckets carried en-axn endless carrier each of which are adapted to -registei' and project atone end 'intora car- :ton carried :on an endless conveyer :andto deposit in said cartons .a predetermined "quantity of granular -or .flaky substance which has been deposited into each bucket in its passage beneath the spout of a bin or reservoir.

Another object of my invention is to provide each of 'such'filling buckets with an inner adjustable wall which may be regulated to control the capacity thereof according to the density of the "substance being handled and thus determinethe quantity deposited into each carton.

Still another object thereof is to produce means for conveying the. empty cartons to the operator to be inserted in position upon the conveyer, and means for maintaining v the properly spaced position upon said conveyer. 1

A still further object of my invention is to produce an attachment for agitating the cartons after they have been filled in their passage on the conveyer to settle and compact the contents, and for other purposes to be hereinafter more fully set forth. To these ends my invention includes the combinations and arrangement of component parts to be hereinafter described and more particularly pointed out in the claims. In the accompanying drawings, in which like reference characters indicate similar ,parts, 'Figure l is a side view of my invention; 2 is an end view thereof; Fig. 3 is :a View of the opposite end; Fig. 4 is a plan view thereof, and )Fig. 5 is a detail sec- 5 aerial View 'of we of my hudkets.

Rig. 6 is a transverse side view of the same, {partly in crosssectien; Fig. -7 is a 'top plan view of one of said filling buckets taken on the lines 7-4 of Fig. 5 showing a pivoted lever "for operating the false wall thereof; Big. 8 -is a similar view showing the means for fastening the buckets upon the endless chains; Fig. 9 is a detail .plan view 'of my device for feeding empty cartons upon the cenveyenand -Fig. .10 is a detail view of-lny means for agitating the cartons to settle the contents therein.

My invention includes, generally, a ipluarality of filling buckets carried on an endless chain, each 'ef which are open at the. top "to :receive --a charge of [material from a reservoir 01' bin, and each being provided with=a pivoted bottom orgate carried on an arm adapted to be automatically opened to dump the contents thereof, and with an adj'ustable wall adapted to be regulated from without to control the cubic capacity thereof; :an endless conveyer beneath said chain of filling buckets and placed on a relatively retreating planei; said conveyer being timed in its "travel to coincide with said chain, and adapted to carry a plurality of cartons which in their initial :position thereon telescope vsaid buckets, but which in their :passage become disengaged therefrom, after being filled by the retreating relative angle cf the conveyer to the bucket carrier; an

end-less traveler provided with a. plurality of spacing fingers adapted -to retain the cartons in ,proper position 'on the conveyor;

an agitator beneath said carton conveyer I adapted to settle and compact the contents of the cartons; and a feeding and delivering for conveying the empty cartons adjacent to their point :of entry upon the endless conveyer, said cenveyer and delivery being timed \to accord with the travel 'of the filling 'convey er.

Referring now to the drawingsfl and 1 indicate a .pair -of endless sprocket chains carried on the sprockets 2 and 2 and 3 and 3 rigidly mounted 'on :the vertical shafts 4 and 5. The shaft 5 is an-"idler while-shaft 4 is provided with the beveled gear '6 meshed with the driving gear 7 coupled with a suitab'le driving power. Suitably secured upon said sprocket "chains 1 and l as by brackets 1* are carried a plurality of hopper shaped cr downwardly tapered buckets 8, the up V provided with an arm 8 projecting through an orifice in the back wall of the bucket to contact with an adjustable bar 12 beneaththe filling chute 10, which may be regulated to press said "false wall 8 inwardly apredetermined distance to adjust the cubic capacity of each bucket when being filled. It will be apparent that when the buckets in their travel pass out of contact with said adjustable bar, said t'alse wall will drop back in normal position and lie upon the outer wall of the bucket. 'Each of said buckets is open at the top, but adjacent to the bottom is provided with a gate 11 by which the contents are held therein and automatically dumped into the cartons. In the present embodiment of my invention, said gate is carried on a lever 11, which is fulcrumed intermediate of its ends on the side wall of the bucket at 11" with the free end of the lever projecting beyond the wall to be engaged by a beveled bar A to raise or open the gate at the proper time and discharge the contents of the buckets. As shown in the drawings, the gate 11 enters the bucket through a slot in one wall, the edges of which are provided with out-turned lips a and b to guide it in position.

Beneath the string of buckets, thus described, I provide a conveyor B comprising an endless belt 12 carried on horizontally disposed drums 13 and 13, one of which is suitably belted with. the driving shaft 25 by the belt 26 and. timed to travel coincident with the sprocket chains 1 and 1*. As shown in the drawings the outer drum 13 is on a lower plane than drum 13 by which arrangement the belt slants away from the horizontally disposed sprocket chains and buckets above same to automatically disengage the cartons carried on the belt as they reach the end thereof.

The empty cartons C are delivered adjacent to the end of the conveyer B and the drum 13 by means hereinafter described,

, and as the buckets charged with the contents turn about the sprockets on the shaft 4., a carton is telescopcd-upon the lower end of each bucket anddeposited upon the belt 12 and together travel to the opposite end of the conveyer. The lever 11 is tripped and the gate 11 of each bucket is opened automatically when the carton is adjusted on the belt and the contents of the bucket deposited therein.

Owing to the fluffy character of the granular contents, it is necessary to settle or compact same within the carton. For this purpose I provide a longitudinal table 1 1 supported on pivoted adjustable links 14 between the upper and lower portions of the belt 12 adapted to support the upper portion of the conveyer on which the cartons travel. The height of said table may be adjusted by shifting 'the angles of said links. Beneath this table 14, is mounted a longitudinal' shaft 15, suitably connected with power for revolving same, intermediate the ends of which it is provided with cranks or eccentrics 15 on which are mounted the pitmen 15 extending upwardly. These are bent to avoid the lower portion of the belt 12 and support the longitudinal board 16 beneath the tablel4, and by which the conveyer belt may be vibrated or agitated vertically. It will be appreciated that the violence of this action may be regulated by relative height of the table 14 as adjusted on the link supports, as the thrust thereof may be thereby adjusted to be accommodated to the condition of the contents of the cartons.

The vibrationof the belt and cartons thus described would tend to displace the cartons on the conveyer, and to overcome this action, I provide an endless traveler 17 comprising a sprocket chain 17 carried on sprocket wheels 17 and 17 mounted on the shafts 4: and 5. which is provided with a plurality of pivoted fingers properly spaced to engage eachof the cartons and holdthem in spaced position on the conveyer and beneath the filling bucket-s.

The empty cartons are delivered to the receiving end of the conveyer by the belts Said belts are carried on the drums 20 beneath the filling buckets as they successively approach the end of the conveyer by the pivoted arm 21 operated by the disk 21 and eccentric pin 21" mounted on the shaft 4 and thus timed to accord with the travel of the filling buckets 8. Adjacent to the outer or free end of said arm 21 is secured a cross bar 22 on the ends of which are .secured the uprights 22 pr0jecting upwardly on either side of the ends of the delivery belts 18 and 19. On the outer or upper ends of each of the uprights is attached the brackets 23 projecting inwardly and adapted to alternately shift the cartons from the ends of'the delivery belts tothe table 20 as they oscillate wit-h the arm 21, when the carton may be readily telesc oped upon the end of the filling bucket just coming into position therefor.

The construction and operation of my invention may be readily understood from the foregoing description and by reference to the accompanying drawings, and it will be appreciated that the parts and combinations thereof may be varied -or modified within a Wide range from the specific exemplificatio-n shown without departing from the spirit and scope, of my invention.

Having thus described my invention, what I claim as new, and desire to be 'secured by Letters Patent, is

1. In a carton filler, the combination with a traveling coiiveyer for carrying a plu rality of cartons, of a plurality of traveling buckets adapted to be successively charged with contents for said cartons, an adjustable inner wall in each bucket, means for successively adjusting the position of said walls while the buckets are being charged, and means for successively discharging the contents thereof into said cartons, substantially as described.
